About Me & Skill Matrix

S Adithya Nachiyappan

Machine Learning Engineer · VIT Vellore '26

I'm an Information Technology undergraduate at VIT Vellore (CGPA 9.00/10.0) focusing on practical machine learning systems, computer vision, and backend data engineering.

Rather than relying on canned benchmarks, I enjoy building models from the ground up to solve concrete engineering challenges — whether that's manually annotating a 1,000+ image dataset for child emotion detection (AttentioMate), training Bi-LSTM/GRU neural networks for deepfake video detection (DeepDetector), or optimizing local offline RAG pipelines with zero cloud API costs (EasyLLM).

During my internships at Aspire Systems and Qube Cinemas, I shipped production pipelines that reduced infrastructure operational costs by 70% and enabled automated document intelligence. I am seeking roles in Machine Learning, AI Engineering, Data Science, or Software Engineering.
